MaiLi is a new hyaluronic acid dermal filler line from the well-known Sinclair. MaiLi is manufactured to refine details, fill folds and wrinkles, and create radiance. MaiLi is manufactured with innovative techniques that help to reverse the sign of aging without losing movement and facial expressions. Sinclair has developed the Smart Spring Manufacturing Technology which gives a soft and supple gel that acts with a spring-like elasticity. This makes the filler integrate more smoothly with high elasticity allowing facial movements to come through with the use of less product. MaiLi comes in four gels, each fine-tuned to reshape, refine, and enhance areas of the face where treatment is needed. All gels contain lidocaine.
